Not all high-end watches have to look boardroom ready. The Bell & Ross Military Ceramic Watch ($4,500) features a self-winding movement, a power reserve of 40 hours, and high-precision adjustment in four positions — all high-end features — but adds a bush-ready matte khaki ceramic case, rubber and heavy-duty synthetic fabric straps, a matte black steel buckle, and a no-nonsense black dial with photo-luminescent numerals, index, and hands.

Planning on visiting the bottom of the sea? Keep track of the hours you spend battling the Kraken with the Rolex Deepsea Challenge Watch ($TBA). Designed for James Cameron's Deepsea Challenger expedition, this unique timepiece features a super-thick body, a black bezel to contrast with the steel case, luminous hands and hour markers, and water resistance down to 12,000 meters, or nearly 40,000 feet, or deep enough that the time should be the least of your concerns.

Who said a watch needs to be digital to have an unorthodox interface? The Harry Winston Opus 12 Watch ($258,000) is an exercise in high-end watch wizardry, built around 12 pairs of hands that point towards the center and rotate in place to turn blue when they're telling the time or silver when they're inactive, a retrograde hand near the center to show precise minutes (from one to five), a tiny seconds hand in the dead center, and a power-reserve indicator in between. Other features include a polished 18K white gold case and buckle, a black alligator leather strap, and the exclusivity that comes from being limited to just 120 pieces worldwide.

Protein bars usually contain as much sugar as a doughnut and have an ingredient list that requires a doctorate to pronounce. RXBARs are different. With no more than eight ingredients, each bar contains only real, whole foods and delivers 12g of quality protein without any added sugar. At the core of every bar is a mixture of egg whites, fruits, and nuts — which they print right on the front of the package — and each of their 12 flavors are gluten-, soy-, and dairy-free. Our favorites are Chocolate Sea Salt, Blueberry, and Peanut Butter, but we recommend starting with the best seller pack, which comes with six of their top selling flavors. Keep a few of these in your gym bag, office drawer, and kitchen pantry for when you need a snack and resist the urge to scarf a candy bar.

When Casper entered the mattress market a few years ago, they changed the mattress industry. And now, after 30 engineering improvements and nearly half a million happy customers, the Casper mattress is more breathable and comfortable than ever. Each mattress is made of multiple layers of foam, including one for support and pressure relief, and one to make sure you sleep cool and comfortable. It's all wrapped up in a durable woven cover, and shipped right to your door in a box that's easy to maneuver into even the smallest homes or apartments. You get 100 nights to try it out and can return it for free if you're not satisfied.

Looking for a more traditional way to keep track of the time across multiple time zones? The Rolex Sky-Dweller Watch ($TBA) should do the trick. This unique timepiece features a inner ring that keeps track of the time at home, traditional hour, minute, and second hands for local time, an advanced date function that knows the difference between 30- and 31-day months, and ring command bezel that lets you quickly and easily choose which function to set using the winding crown.

You don't need to be a pilot to appreciate the Omega Spacemaster Z-33 Watch ($TBA) — but it doesn't hurt. Designed with flyboys in mind, it features standard analog watch hands, as well as two transreflective LCDs with red letters set into the non-reflective matte black dial, which serve as the basis for a host of features, including date, UTC, two time zones with 12- or 24-hour display, an alarm, a perpetual calendar, a chronograph, a countdown timer, and a flight log with ten slots. Oh, and its grade 5 titanium case is water resistant to 100 feet — but if you've found yourself in water, the well being of your watch is probably the last thing on your mind.
